Secure treatment for high oil content sludge Problem An instant coffee manufacturer in Thailand had dewatered sludge with a filter press. 10 to 20 percent of the coffee beans is oil, which has caused clogging of the filter and trouble to stop the equipment for maintenance. AMCON's offer for a solution The self-cleaning ...

YEAR: 2009 COUNTRY: BELGIUM N° and MACHINERY MODEL EMPLOYED: 12 GHT 2000.P19 MEM Diemme® Filtration In Antwerp Harbour, lots of sediment accumulates, equal to 600,000 tons of dry material, which caused a gradual decrease in depth with the consequent reduction in navigability. Since a few years ago, the ...

Strategies for a sustainable and safe sludge removal Wastewater (WW) treatment and the management of sludge produced are global issues, with growing challenges, that must address the concerns of all of the stakeholders, including the facility administrators and operators, the regulators, the politicians, the scientific community, the wastewater generators, the taxpayers and the general ...

Dewatering sludge at wastewater treatment plants has traditionally been a major operational concern. Most large operations must use mechanical filter presses or centrifuges to efficiently dewater their sludge. For many smaller operations, however, this equipment is too expensive and too large for their needs. Therefore, many smaller facilities rely on the sand filter drying beds for sludge ...

Due to our past successes with this corrugating corporation, Integrated Engineers was asked to solve a major wastewater problem with their new wastewater treatment system. The company had recently purchased a wastewater treatment system and were having problems with these issues: • Lack of support from the systemsupplier• Several mechanical problems with thepumps, controls and filter ...

Introduction – the History of Beer The origin of beer was a happy coincidence: In the fourth millennium BC, the Sumarians discovered the fermentation process. The country of the Sumarians, called Mesopotamia, was located between the Euphrates and the Tigris. The Sumarians wanted to help an ill person swallow some bread, so and they soaked a piece in water. They simply forgot the bread in ...

During the process of wastewater treatment, sludge generation is an important and at times crucial issue to be addressed as inadequate sludge handling system can pose serious environmental implications. Liquid sludge can be easily thickened and reduced to a solid cake via sludge thickening / dewatering. This reduces the volume of liquid sludge significantly, usually resulting in a quite ...

OverviewThe paper mill at Valdivia produces card board from chemical and mechanical pulp. With the installation of an additional paper machine, the wastewater flow increased from 4,000 m3/d to 8,500 m3/d and therefore an extension of the existing wastewater treatment plant was required. RequirementSo far, the existing effluent treatment plant consisted of a primary ...

ABSTRACT The basic principles of batch thermal hydrolysis process (THP) are well known as a pre-treatment to anaerobic digestion (AD) . Early work done in the 70s in the USA and the 80s in Japan demonstrated the optimum time and temperature for thermal hydrolysis being 340 F for 30minutes. These principles have been put into full practice in 20 plants around the world at plants ranging from 5 ...

ABSTRACTThe Des Moines Wastewater Reclamation Authority operates a 97-million gallon per day regional wastewater reclamation facility (WRF) largely constructed in the mid 1980s to serve the greater Des Moines, Iowa metropolitan area. Originally constructed in a largely rural area, current plans for the area around the WRF establish a need for emissions control to reduce offsite odor impacts, in ...

Original story at MIT News Jeffrey Grossman applies new materials research to making desalination cheaper and more efficient. With the intensifying drought in California, the state has accelerated the construction of desalination plants. Yet due to high construction and operating costs, as ...

Simple and inexpensive, Geotube dewatering technology can make management of tailings and fines much easier. Many aggregate plants experience high equipment and manpower costs associated with the handling and removing o( tailings and fines from settling ponds. The costs of maintaining pond operations can vary significantly from plant to plant. Not only is valuable space tied up ...

Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

In 1990, the International Agency for Research on Cancer (IARC), an agency of the World Health Organization (WHO), published their findings on chromium and chromium compounds as carcinogens. Chromium may be isolated in any of three volume states: Chrome 0 or metallic chromium; Chrome III called “Chrome 3” or Chrome VI called “Chrome 6,” also called hexavalent ...

What is wastewater? Wastewater, the waste discharge that first comes to mind in any discussion of stream pollution, is the discharge of domestic wastewater, which contains a large amount of organic waste. Industry also contribute substantial amounts of organic waste, some of which comes from vegetable and fruit packing; dairy processing; meat packing; tanning; processing of poultry, ...

The Hybrid ZLD approach pairs the best of membrane and thermal technology to make ZLD affordable, yet robust and reliable. Over the past decade, the Hybrid ZLD systems i.e. integrated zero liquid discharge (ZLD) systems have emerged as die most effective ZLD approach for dealing with the most difficult to treat wastewaters in many industries including power, refining, and chemicals. The Hybrid ...

The City of Springfield, Ohio, recently opened its 100 MGD enhanced high-rate treatment facility, designed to treat and disinfect combined high-volume stormwater and wastewater flows generated by wet-weather conditions. Utilizing EPA-documented Compressible Media Filtration technology – FlexFilter™ from WesTech – the system can also provide tertiary filtration and disinfection ...
